Plone: Overrides.zcml gets auto-included with z3c.autoinclude

Unsurprisingly, specifying a z3c.autoinclude entry point in your Plone product egg means your ZCML gets automatically included. That’s great because it means you don’t have to specify your product under the ZCML section of your instance in buildout. One thing that isn’t so obvious (it’s not mentioned that I can see on plone.org) is that if your package is marked for ZCML autoinclude, then Plone will automatically load an overrides.zcml file in your product.

Nothing hits you like a slippery wet fish in the face more than hitting this issue and having it …

(Lack of) Kupu CSS Styles, Plone and Deliverance

Note: see this post for up-to-date details.

Essentially, the issue is that Deliverance doesn’t theme (and rightly so) the Kupu editor within Plone and hence any styles applied to normal pages by Deliverance don’t show up.  My workaround, as detailed on that post, is to customise the “emptypageresources” page template and include a suitable link to the CSS file, like so:

<link href="site.css" type="text/css" rel="StyleSheet" tal:attributes="href string:${context/@@plone_portal_state/navigation_root_url}/static/theme/site.css;" />

(changing the tal:attributes section accordingly).  This should introduce perfectly correct styles for your editor from your …

David tries Plone 4.0a2 (Part 2)

Rightio!  So we’ve got Plone 4.0a2 installed and up and running.  Boy, she looks sweet:

• The new Plone site setup is flawlessly simple.  No more ZMI for those of us that don’t want to use it.  It’ll always still be useful, but having Plone throw up a simple, no no-nonsense front-end installer is just what it needed.  Other PHP based CMSes always had it too easy ;-)
• Editing view:  clearer tabs at the top (no idea how many clients miss those, me included to start!) and resizable editing fields.  Great. TinyMCE as the editor — just what the …

Deliverance, Plone, and tags

It’s been a little bit of time since my last post, and who can blame me with my site having been down for almost 2 full days over the last week!  I’m not paying that much for the webspace, thankfully, but if I was, I’d be seeing red over it.  Apparently some patch for MySQL broke everything; imagine how it looked to see my site with a ‘500 internal error’ plastered all over it and not being able to access my cPanel. Ugh.

Anyway, everything’s back again, assuming that you can see this.  Okay? Great!

Deliver me from … Deliverance?

Always one for being on and beyond the bleeding edge of new technology, I’ve (with the help of colleagues) been setting up a new technology for applying themes to web sites.  In particular, I’m applying Deliverance to Plone and whilst I’m not the first one to venture out into the wilderness this way, I’ve got to be thinking that I could be one of the few people documenting their experience.  Ah, but where to begin?

Plone: Re-ordering Viewlets

Just responded to a post on the Plone Nabble forums (here) about how to re-order viewlets.  In particular, this one is little different (but not terribly so) because the original poster wanted to put the breadcrumbs above the global sections (global tabs in Plone).  Normally, this is straight forward because you just use a Generic Setup profile (viewlets.xml) and use an order manager to move your viewlet.  This, however, is a teeny bit more complicated because you’ve got one viewlet that’s outside of another viewlet manager.

Without further ado, my post from the forums:

User-selectable Themes In Plone

It’s something I came across a while ago, but wasn’t exactly something that stayed in the fore-front of my mind: how to let users choose or select a theme (arbitrarily) on a Plone site.  Normally, I stick to having one theme per site for continuity but a new theme-test site for clients is an exception.

If you were to search Google for the right terms, you’ll find out how to let this happen, but I ended up having to go hunt it down myself. Hopefully this entry will help people (if I go and include as many …
